Cancer of unknown primary is defined as a metastatic disease present in the absence of an identifiable primary site of origin. Squamous cell carcinoma (SCC) of unknown primary is a relatively uncommon subtype that usually involves metastases to the cervical or inguinal lymph nodes. We present a rare case of SCC of unknown primary metastasizing to the gallbladder fossa and creating a duodenal fistula. This case highlights the rarity of SCCs in the gallbladder region and the risks posed by chemotherapy in patients with gastrointestinal fistulas.
原发灶不明的癌症被定义为在没有可识别的原发部位的情况下出现的转移性疾病。原发灶不明的鳞状细胞癌（SCC）是一种相对不常见的亚型，通常会转移至颈部或腹股沟淋巴结。我们报告一例罕见的原发灶不明的鳞状细胞癌转移至胆囊窝并形成十二指肠瘘的病例。该病例凸显了胆囊区域鳞状细胞癌的罕见性以及化疗对胃肠道瘘患者带来的风险。
